Possible Causes
Freeze sensor reading out of range, Sensor cable damaged, Control firmware detecting unsafe low temperature, Sensor dislodged from mounting point
How to Fix / Troubleshooting
Safety first: Disconnect power before moving or adjusting the spa.
- 1. Protect from freezing: If ambient temperatures are near or below freezing, move the spa to a more sheltered location or insulate the pump unit. Frozen water can damage components.
- 2. Allow temperature to normalize: Let the spa sit powered off until water and ambient temperatures are above freezing, then power back on and check if E13 clears.
- 3. Inspect sensor leads (if visible): Look for any external sensor wires that may have been pulled loose or damaged.
- If E13 continues in normal temperatures: The freeze sensor or control PCB is likely faulty. Contact Lay‑Z‑Spa support for diagnosis and possible pump/heater unit replacement.
